NGC Ancients: Coins We Grade
We attribute and grade most coins struck in the Western World from the origins of coinage through c. AD 500, as well as most coins of the Byzantine Empire (AD 491-1453).
Coins Not Eligible for NGC Ancients
NGC Ancients will not grade coins that are of an ineligible type, are altered, appear to be unstable (internally or on the surfaces), which cannot be verified as authentic, or which do not have sufficient design detail to allow a minimally acceptable attribution. In these cases, fees are assessed as handling costs and insurance expense have been incurred, and the graders have engaged in the normal examination process in order to determine that a coin must be returned ungraded.
NGC Ancients will only grade coins it believes to be genuine. Coins considered counterfeit will be returned ungraded with the note, "NOT GENUINE." Also, NGC Ancients will not grade coins if authenticity cannot be ascertained by our staff experts and/or our network of consultants. In such cases, coins will be returned with the comment "AUTHENTICITY UNVERIFIABLE." This latter category may include coins considered genuine by other experienced professionals in the field.
While we make every effort to rely on the best information available, due to the inconsistency of opinions on these matters in the marketplace, no guarantee is made or implied about the authenticity of coins graded by NGC Ancients.
Coins with significant or deceptive surface alterations are ineligible for grading.
Ancient cast coins are ineligible for the services of NGC Ancients. Though the vast majority of ancient coins were struck, some issues were manufactured through a casting process. Distinguishing between original cast ancient coins and modern castings is often difficult, and for this reason cast coins are ineligible for NGC Ancients grading, even if we believe them to be genuine. It was a common practice for ancient coins to be struck on cast planchets, and sometimes indications of that casting survives the striking process; this, of course, does not affect the eligibility of struck coins for grading.
Fragile or unstable coins (and those suspected of being fragile) are not eligible for encapsulation. Where possible, fragile coins will receive Photo Certificates in lieu of encapsulation.
Scyphates and Sasanian
Though NGC Ancients does grade gold, electrum and silver scyphate (cup-shaped) coins of the Byzantine Empire, for reasons of accuracy of attribution and physical characteristics, we do not grade copper or billon scyphates of the Byzantine Empire or its related empires. For similar reasons, we do not grade Sasanian coins, even if they were struck prior to c. A.D. 500. Specialized groups or collections of this material may be considered for grading on a case-by-case basis.
India and Other Eastern Coinage
Though we do grade Bactrian, Indo-Greek and Indo-Scythian coins, NGC Ancients currently does not grade coins from ancient India (including Kushan) or from any region further east. The lone exception in the Kushan series is the 'Soter Megas' bronze coinage, which at present we do grade.
